find an equivalent expression to 3 (4m-2)-2(m+5). write your answer as an expression with two terms
Answer:
10m - 16
Step-by-step explanation:
3 (4m-2) -2(m+5)
The equivalent expression can be simplified as an expression with two terms as follows:
3 (4m-2) -2(m+5)
Open each parenthesis by multiplying the outside value with the values in the parenthesis.
3 (4m-2) = 12m - 6
-2(m + 5) = -2m -10
Bring the value together
12m - 6 -2m - 10
collecting like terms
12m -2m - 6 - 10
10m - 16

What is 10.49 seconds rounded to the nearest second
Given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.
Recall:
When rounding a number, if the number that comes before it is 5, 6 and up to 9, you round the number up. i.e. 57 to the nearest ten would be rounded up to 60.
When rounding a number, if the number that comes before it is from 4 below, you round the number down. i.e. 54 to the nearest ten is 50.
Thus:
Given 10.49 seconds, we want to round the number to the nearest second.
We need to round it down.
Therefore:10.49 to nearest seconds = 10 secs.
In summary, given 10.49 seconds to be rounded to the nearest second, we would round down 10.49 seconds to have: 10 seconds.

Evaluate 3x + y when x = 1/3 and y = -7/4
Write the answer in simplest form
The expression 3x + y simplifies to -3/4 when x equals 1/3 and y equals -7/4.
Explanation:To evaluate the expression 3x + y when x = 1/3 and y = -7/4, we simply substitute these values into the expression.
So 3x + y becomes 3*(1/3) - 7/4, which simplifies to 1 - 7/4.
To simplify this further, we convert 1 (which is the same as 4/4) and -7/4 to have the same denominator (which is 4). So, 4/4 - 7/4 equals -3/4.
So, the simplest form of 3x + y when x = 1/3 and y = -7/4 is -3/4.

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?
The football team lost 4 yards on 2 plays in a row, resulting in a change in field position of -8 yards.
Explanation:The football team lost 4 yards on 2 plays in a row. To determine the change in field position, we need to subtract the total yardage lost from the starting field position. Assuming the starting field position was at the 50-yard line, the change in field position would be -4 yards x 2 plays = -8 yards. Since the team lost yardage, the change in field position would be a negative value.

At one time, the Texas Junior College Teachers Association annual conference was held in Austin. At that time a taxi ride in Austin was $1.15 for the first 1/5 of a mile and $0.35 for each additional 1/5 of a mile. If the distance from one of the convention hotels to the airport is 8.5 miles, how much will it cost to take at taxi from that hotel to the airport? (Round your answer to the nearest cent.)
To calculate the taxi fare, we determine the cost for the first 1/5 mile at $1.15, and then add the cost for the remaining increments at $0.35 each. The total fare comes to $15.68 when rounded to the nearest cent.
To calculate the cost of a taxi ride in Austin from one of the convention hotels to the airport for an 8.5-mile distance, let's break it down step by step:
The initial fare covers the first 1/5 mile and costs $1.15.Since the total trip is 8.5 miles, we need to find out how much the remaining 8.3 miles (8.5 miles - 1/5 mile) will cost at $0.35 per each additional 1/5 mile.To find the number of 1/5 mile increments in 8.3 miles, we divide 8.3 by 1/5, which equals 41.5 increments.Now we multiply the number of increments (41.5) by the cost per increment ($0.35), which equals $14.525.Adding the initial fare of $1.15 to $14.525 gives us the total cost of the taxi ride, which is $15.675.Finally, we round $15.675 to the nearest cent to get $15.68 as the total cost of the ride.Therefore, the taxi fare from the hotel to the airport will be $15.68.
06.01) Saturday morning there were 7 adults and 20 kids at Pump and Jump Land. The morning cash registers show $236 was collected. In the afternoon there were 21 adults and 50 kids for a total amount of $618. What is the cost for 1 adult?
The cost of 1 adult for the given games using the various parameters to create a simultaneous equation gives; $8
How to create simultaneous equations?
Let cost of adults be x and let cost of kids be y.
Now, there were 7 adults and 20 kids at Pump and Jump Land and the cash collected was $236. Thus, we can say that;
7x + 20y = 236 -----(1)
Similarly, there were 21 adults and 50 kids for a total amount of $618. Thus;
21x + 50y = 618 -----(2)
Solving both equations simultaneously gives;
x = $8 and y = $9
Thus, cost of 1 adult = $8
